win32实现List Control

到目前为止，还没有正儿八经的写过MFC程序，虽然现在自己把MFC的框架看得差不多，但是还是不想

使用MFC写代码，做界面MFC是关键，这是谁也无法逃脱的框架，好了，废话少说，说说自己的实现。

List Control是Windows的控件，使用的时候要加#include #pragma comment(lib, "commctl32.lib"（

这是win32平台，若是wince平台则不需要，原因现在我还不清楚） .

1.创建List Control控件

m_hList = ::CreateWindow(L"syslistview32", L"", WS_VISIBLE | WS_CHILD | WS_BORDER |
								LVS_REPORT | LVS_SHOWSELALWAYS, m_pt.x, m_pt.y,
								m_sz.cx, m_sz.cy, _hParent, NULL, _hInst, NULL);

 

2.创建加列项目

 LVCOLUMN _lvcol;
 memset(&_lvcol, 0, sizeof(LVCOLUMN));
 _lvcol.mask = LVCF_TEXT | LVCF_WIDTH | LVCF_SUBITEM;
 _lvcol.pszText = "sdfsdfs"
 _lvcol.cx = 80;
 ::SendMessage(m_hList, LVM_INSERTCOLUMN, 0/*第一列*/, (LPARAM)&_lvcol);

 

 

3.添加列元素

a.第一种方法

 LVITEM _lvitem;
	memset(&_lvitem, 0, sizeof(LVITEM));
	_lvitem.mask = LVIF_TEXT;
	_lvitem.cchTextMax = MAX_PATH;
	_lvitem.iItem = _iItem;
	_lvitem.iSubItem = _iSubItem;
	_lvitem.pszText = _text;
	::SendMessage(m_hList, LVM_INSERTITEM, _lvitem.iItem, (LPARAM)&_lvitem); 

 

b.第二种方法

 LVITEM _lvitem;
	memset(&_lvitem, 0, sizeof(LVITEM));
	_lvitem.mask = LVIF_TEXT;
	_lvitem.cchTextMax = MAX_PATH;
	_lvitem.iItem = _iItem;
	_lvitem.iSubItem = _iSubItem;
	_lvitem.pszText = _text;
	::SendMessage(m_hList, LVM_SETITEMTEXT, _lvitem.iItem, (LPARAM)&_lvitem);

 

4.删除已经选择项目

_lvitem.iItem = ::SendMessage(m_hList, LVM_GETNEXTITEM, -1, LVNI_SELECTED);
	if (-1 != _lvitem.iItem) 
	{
		::SendMessage(m_hList, LVM_DELETEITEM, _lvitem.iItem, 0);
        }

 

我写了类，下面是代码：

1.头文件：

	TCHAR _path[MAX_PATH];
	PLSTELE next;
};


class KListCtrl
{
public:
	KListCtrl();
	KListCtrl(HINSTANCE, HWND, POINT, SIZE);
	~KListCtrl();

	void CreateColumn(UINT _mask, int _cx, TCHAR* _text, int _col);
	void SetListItem(int _iItem, int _iSubItem, TCHAR* _text);
	void SetListItemText(int _iItem, int _iSubItem, TCHAR* _text);
